what is even considered as an extracurricular for summer programs?

i'm applying to sumac and sams, and im very confused as to what is considered an ec and what isnt.

for reference here is a vague summary of my ecs:

3 science fair projects, volunteering, 2 small python personal projects, 4 muns, 1 big python course (cs50p)

i've cleared AMC and IOQM, so should i mention that in my ecs or not ? i'm planning not to as they clearly are awards, but who knows 😭😭

along with this, i also regularly play bball but havent won any big tournament (all were interschool), so should i list that in my extracurriculars as well?

will the big python course (cs50p) be considered as an ec? it took me 3 months and i did make some cool projects as assignments

when does something stop becoming an ec? for instance is listening to music an ec? should i put it down even tho i do it purely for contentment, and dont add any value by doing so ?

sorry for the long post

any help is appreciated 🙏
